I love it and will use this term at the first opportunity!
Your extended family sound rather onto it- although moving to full self custody is hopefully their next move.
ETFs and MSTR are rat poison, imo.
Of my extended family only sister ever bought Bitcoin - I gave up trying to convince them otherwise long ago.
Sister works in finance as a lawyer for one of NZs larger non bank lenders and wanted to learn more and understand it as it is/was obviously a new and interesting concept, but I think she is still mostly loyal to the fiat debt slavery system that pays her salary!
